thanks for the feedback. What I forgot to mention was that the fuel gauge showed about 1/3 when we started, but had dropped to near empty after 30-45 minutes. If I rule out a defective fuel gauge, it looks like we have a fuel leak. I smelled the water that's peeing out of the engine and noticed a trace of fuel, but I'm not sure if that's normal.
Could a leak allow water to enter the fuel system?
If a visual inspection of the system doesn't show a problem, then how do I do a pressure test of the fuel system?
